@@ -39,3 +39,22 @@ kopia repository server setup (on a non-NixOS host at the time):
* kopia server start --address 0.0.0.0:51515 --tls-cert-file ~/kopia-certs/kopia.cert --tls-key-file ~/kopia-certs/kopia.key --tls-generate-cert (first time)
* kopia server start --address 0.0.0.0:51515 --tls-cert-file ~/kopia-certs/kopia.cert --tls-key-file ~/kopia-certs/kopia.key (subsequent)
[TLS is mandatory for this]
NFS services server setup (one-time on the NFS server host, e.g. zippy):
* sudo btrfs subvolume create /persist/services
* sudo mkdir -p /persist/root/.ssh
* sudo ssh-keygen -t ed25519 -f /persist/root/.ssh/btrfs-replication -N "" -C "root@$(hostname)-replication"
* Get the public key: sudo cat /persist/root/.ssh/btrfs-replication.pub
Then add this public key to each standby's nfsServicesStandby.replicationKeys option
NFS services standby setup (one-time on each standby host, e.g. c1):
* sudo btrfs subvolume create /persist/services-standby
Moving NFS server role between hosts (e.g. from zippy to c1):
See docs/NFS_FAILOVER.md for detailed procedure
Summary:
1. On current primary: create final snapshot and send to new primary
2. On new primary: promote snapshot to /persist/services
3. Update configs: remove nfs-services-server.nix from old primary, add to new primary
4. Update configs: add nfs-services-standby.nix to old primary (with replication keys)
5. Deploy old primary first (to demote), then new primary (to promote)
